hello,
I have a lot of subfolders in my outlook. So when I want to find some special emails I need to open all subfolders to check. So I have to expand them one by one manually.
But it's easy to colse them all, just click to collapse the root of the pst file. So I hope I can quickly expand all subfolders by only clicking a button or something else just like I close them. How to set it in outlook?
